IMPROVEMENT IN MINERS LAMPS.

Specification forming part of Letters Patent No. 217,791, dated July 22,1879; application filed May 17, 1879.

To all whom it may concern.-

Be it known that I, JOHN H. GABLE, of Shamokin, in the county of Northumberland and State of Pennsylvania, have invented a new andvaluable Improvement in Miners Gap-Lamps; and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of my improved lamp inperspective View.

Fig. 2 is a vertical section of the same. Fig.3 is a similar detailsection, and Fig. 4 is a crosssection through the wick-tube.

This invention has relation to miners caplamps, or lamps which areattached to the front of the hat or cap; and it consists in thearrangement and novel construction, in con nection with the body of sucha lamp, of a transverselyflattened spout-burner, whereby the flow of oilis better controlled and the light very much enhanced, as h'erei n aftershown and described.

In the accompanying drawings, the letterA designates the body of aminers lamp, having at its back the usual hook (0, whereby it isattached to the hat or cap in the ordinary manner.

It has been customary to provide the front of this lamp with a wickspout or burner, of round .or other form, quite as thick as it is wide,whereby a compact and heavy flame is produced, better adapted for givingheat than light.

My improvement consists in making this wick-tube or burner-spout intransverselyflattened form, the narrow diameter being in the plane ofthe attachment-hook, while its flat faces or walls are laterallyextended. This spout extends above the body of the lamp, and holds aflat wick, e, which lies transversely therein and allows the oil to flowfreely to the end of the burner, as well at each side as in the middle.Sometimes the spout is made a little wider and broader at the lowerportion, so that the oil will more easily reach the wick in the burnerend. The flame formed by this trallsversely-flattened burner is broadand thin from front to rear, its lateral expansion giving it more powerin front, where itis especially needed, than at the sides. Being thin,it is not so heating to the head as a heavy round flame, and it is notso apt to smoke.

This burner will burn any oil to greater ad vantage than the roundburner, and will effect a saving of oil and wicking.

I am well aware of the flat wiek-tubes in usein household lamps andlanterns; and therefore make no broad claim to a flattened wicktube.

That I claim, and desire to ters Patent is- In a miners lamp having arear attachmenthook, a transverselyflattened spout-burner, extendingupward from the front of the body, having its small diameter in theplane of the hook, and spreading laterally to form a flame thin at thesides and broad in front, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

secure by Let- JOHN H. GABLE.
